How to Find and Use Styles on the UserStyles.org Archive (uso.kkx.one)

The UserStyles.org Archive at uso.kkx.one is a mirror of the original userstyles.org, described by its operators as an ad-free, spyware-free copy of the site. To use it, browse or search for a style, open its page, and install it through a userstyle manager browser extension such as Stylus. The archive is a source of style files, not a browser add-on itself — you need a manager installed before any style will take effect.

What the Archive Is and What Userstyles Do

Userstyles are CSS (sometimes with a bit of scripting) that restyle websites in your browser: hiding clutter, changing colors and fonts, tightening layouts, or removing elements you never use. The archive preserves styles originally published on userstyles.org, which has changed over time, so links and pages that once lived there can still be found here.

The site itself is a catalog. It does not modify pages on its own, and installing a style does nothing until a userstyle manager extension is active in your browser.

Finding a Style

1. Open https://uso.kkx.one in your browser.
2. Use the site's search or browse listings to locate a style by name, target site, or author.
3. Open the style's page and read the description, the sites it applies to, and any notes the author left.
4. Check the preview or screenshots where available to confirm it matches what you want.

Because this is an archive, expect some entries to be old. A style written for an older version of a website may no longer match the current layout, so treat the description and last-updated information as your main signals before installing.

Installing a Style with a Userstyle Manager

You need a manager extension first. Stylus is the common choice and works in Chrome, Firefox, and other Chromium-based browsers; Stylish and similar managers also exist, though some have had privacy controversies, which is part of why ad-free mirrors like this one exist.

1. Install your chosen manager from your browser's official extension store.
2. On the archive, open the style you want.
3. Use the install link or button on the style page — the manager should intercept it and show a confirmation screen.
4. Review the style's name and the sites it targets, then confirm the install.
5. Visit a target site and reload the page. The manager's toolbar icon should show the style as active.

If the install link does not trigger the manager, copy the style's CSS from its page and add it manually through the manager's "write new style" option, pasting the code and setting the URL match pattern yourself.

Checking Compatibility

After installing, verify on the actual site rather than trusting the preview. If nothing changes, the most common causes are a URL pattern that does not match, another style taking precedence, or a style written for an older page layout.

Common Snags

• Install link does nothing: the manager may not be set to handle style installs; use the manual paste method.
• Style installs but has no effect: check the manager's "applies to" patterns against the page URL.
• Partial or broken styling: the site has likely changed since the style was written; look for a newer entry or edit the CSS yourself.
• Two styles fighting: disable one at a time in the manager to isolate the conflict.

Is It Safe to Use?

The archive describes itself as ad-free and spyware-free, which addresses the main complaint about the original site's later advertising. That claim covers the mirror's own pages, not the styles hosted on it. Styles are third-party code, so review what a style contains before installing — especially anything beyond plain CSS — and prefer entries with clear descriptions and identifiable authors. Install through your manager's confirmation screen rather than running unknown scripts directly.
